15.3%: The rate of underemployment in Idaho, under the Labor Department’s broader definition.

At 7.1%, Idaho’s September unemployment rate is significantly better than the national mark of 7.8%. But by another measure, Idaho’s job market is actually worse than the national average, according to new Labor Department data that paints a more detailed picture of joblessness in all 50 states.

The official unemployment rate uses a fairly narrow definition of “unemployed,” looking only at people who are actively looking for work. But the Labor Department also publishes a range of other rates using different definitions. The broadest and best known alternate rate, known by its Labor Department designation, U-6, includes people who want to work but aren’t actively looking and also people who are working part-time because they can’t find full-time jobs. As of September, the national U-6 rate stands at 14.7%.

More recently, the Labor Department has begun publishing similar data for states. The numbers are released quarterly on a four-quarter rolling average, so they aren’t as up to date as the state unemployment figures that are released each month. Still, they give a window into state labor markets.

On the whole, the U-6 and other alternative measures tell the same story as the official unemployment rate. Nevada, home to the nation’s highest unemployment rate, also ranks worst under all the other definitions. North Dakota, where an oil boom has led the way to the nation’s lowest unemployment rate, also has the lowest U-6, at 6%.

Still, there are a few interesting exceptions. Idaho looks better than the national average in every category except the U-6, meaning the state has an unusually high number of people stuck in part-time jobs. Montana ties with Nevada for the biggest differential between the U-6 and the U-5 (which excludes involuntary part-timers but is otherwise identical), so Montana too has a lot of part-timers, although its U-6 remains a bit below the national average.

On the other hand, Kentucky has an unemployment rate that’s a hair above the national average. But the state does better than the country as a whole in the broader measures, suggesting the state has relatively few workers who have dropped out of the labor force or gotten stuck in part-time jobs. Similarly, Washington D.C. has a high unemployment rate—9.3% over the past year—but a low U-6. In other words, it is tough to get a job in D.C., but if you’ve got one, odds are it is full-time.

Alabama, meanwhile, gets credit for the biggest drop in the U-6 over the past year. A year ago, 17% of the state’s residents were un- or under-employed, one of the worst rates in the nation. In the latest data, that figure has dropped to 13.6%, better than the national average.
